From the oregoing description itwill be obvious that I have perfected very simple, economical, accurate and durable trolley bracketsand clips, which will be li ht in wei ht, and which facilitate the attac ment of t etrolley chain thereto.

What I claim is 1. A carrier trolley for engaging a con- 35 veyor chain, including oppositely disposed pressed steel brackets, the lower ends of which are rigidly secured together in facial contact, and vertically spaced pressed steel clip attachments secured to opposite sides of 9 said brackets for supporting the chain links therebetween. I 2. The combination with a track, of a trolley mounted to travel thereon and including pressed steel brackets substantially U-shaped 95 in cross section, the lower ends of which converge and are rigidly secured together in facial contact, shoulders formed on said brackets, and clip attachments rigidly secured to the lower ends of said brackets and a forming a clevis, the upper ends of said clips being turned, and a chain link interposed between said shoulders and the turned ends of the clip attachments. 8. The combination with a track, and a chain having an opening therein, of a trolley mounted to travel on said track, and including pressed steel brackets, and the lower ends of which conver and extend throu h 4 the openin in the c ain, shoulders on t e no brackets, c 1ps secured to said brackets for limiting the upward movement of the link, and detachable clips secured to the lower end ,of the brackets and engaging said chain for t securing it in osition.

4. The com ination with a track and a chain havin an opening therein, of a trolley moun to travel on the track and including oppositely dis sed ressed steel brackets rigidly secured contact, the lower ends of said brackets being reduced and extending through the chain 0 enmg to permit a cham to be assembled t ereon after the trolley is mounted in position, and clips detachably secured on the lower end of said brackets for securing said chain in position.
